Ullllllllll W. H. HUNT. Vapor Burner.

IVILLIAM H. HUNT, OF BROOKLYN, NEW YORK.

CONSTRUCTION OF VAP OR-BURNERS.

Specification of Letters Patent No. 25,830, dated October 18, 1859.

To all lwhom it 'may concern:

Be it known that I, WILLIAM H. HUNT, of Brooklyn, in the county of Kings, State of New York, have invented a new and useful Improvement in Vapor-Gas Self-Grenerating Burners; and I do hereby declare that the following is a full and exact description.

The nature of my invention consists in so arranging a `vapor gas self generating burner as'to prevent in a great degree the deposit of rosin or other matter from accumulating within or around, and closing the opening, provided for the flow of the vapor of hydro-carbon into the air and vapor mingling reservoir or chamber by combining the conical screw valve-seat chamber and draft holes with the conic frustum of inclined planes radiating from the sharp point of the screw valve downward through the4 draft holes and leading the resinous deposits while in a melted state down into the deposit cup as hereinafter specified and shown.

And it consists also in the manner of constructing the air and hydrocarbon reservoir' and burner separately and of combining them with the conic frustum of inclined planes and draft holes 4and with veach other so as to enable me to clean out from the interior any resinous or other adhering substance which may collect within the reservoir and burner and also enabling me to adjust the position of the light relatively with the pendant, or bracket to which the same may be attached.

And it consists also in the manner of enlarging and diminishing the air of the eXit orifice of the burner at pleasure by the means of combining a damper with, and within, the slot which forms said exit orifice, which damper may be used to diminish the area, or to enlarge it, by turning the same edgewise or if need be it may be taken out of the slat leaving the entire area of the orifice open, by which means I am enabled to graduate the flow of the mingled air and vapor from the reservoir to the intensity and volume required for the amount of light desired.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation; reference being had to the accompanying drawings making a part of this specification, in which- Y Figure l is a sectional elevation. Fig. 2

an end view, (part in section and part eX- ternal).

Like indices refer to like parts in both the figures.

(a) is a reservoir for the reception of the camphene or other fluid, attached to which, by the stoppcock b is the branch pipe o having screwed to its lower end the right angle tube (d, cZ,) which I term the generator. Within the horizontal leg of the generator (d, (L) is the perforation (e) conmmunicating to the vertical passage way (f) which is minutely perforated at the top (g). The capacity of said vertical passage way being regulated by the conical pointed adj usting screw (7L) which when screwed so as to entirely close the passage way projects its point through the aperture (e) into the mingling reservoir, and tends to remove any deposit which may have collected therein. A

The outside shape of the metal, within which is formed the passage way is that of a conic frustum (i) the smaller diameter of which is equal to the diameter of the perforation (g). This shape presents the least possible surface in a plane with the perforation (g) for the lodgment of rosin or other deposits, which retards the flow of gas, and forms an inclination radiating from the perforation (g) down which said deposit can flow, through the holes(K) (K) (I )-which also answer the purpose of draft holes-into the deposit cup, (Z) upon the top of the vertical leg of the generator (d, fZ,) is screwed the cap piece (m) having cut in its top the oblong orifice at which point the gas is ignited. The area of this orifice (n) may be enlarged or diminished as the intensity of the light is required to be varied, by the damper (o) which isV placed within the slot constituting the eXit, or burning orifice and it being adjustable and kept in place by its own gravity, it may be used to contract the orifice or to enlarge it to its full area, if need be, by removing it entirely, and again replacing it-and thus enabling me to so graduate the flow of mixed air and vapor from the mingling reservoir as to secure the intensity and realism of light desired. On the external sides of the cap piece (m) and extending a suitable distance above the orifice (n) are the copper conducting rings (P, 13,) for conveying a part of the heat caused by the ignition of the gas, at the orificem) to the generator (d, al).

lOl

The branch pipe (c) is supplied with a wick at its lower end, to check in a manner the iiow of camphene or other iuid, and at the same time admit of a gentle feed to the generator (al, d,).

To put the self generating gas into operation, a piece of sponge well saturated with alcohol should be ignited and placed in contact with the generator d, 0Z,) which causes the camphene or other uid, in the passage way (f) to be evaporated, and the vapor to rise up through the perforation (g) Where it comes in contact with the air which is supplied through the draft holes (K) (K) (K) and flowing up through and out of the orifice (n) it becomes ignited, the heat of which being very intense, is partly absorbed by the copper rings (P, 1),) and conducted down the same to heat the generator (d, d,) and thus the generation of the gas becomes self sustaining, after having been thoroughly heated and put into operation artificially as described.

The advantages of this self generating burner over all others, heretofore invented, or of which I have any knowledge, consist in the peculiarity of the conic frustum (i) which prevents rosin or other deposits, from collecting at, and clogging up the perforation (g) which has been the source of great annoyance, and has tended in-a great degree to prevent them from coming into general use. I also consider it particularly useful to construct the burner in such a manner that the cap piece (m) may be readily removed to admit of the tube being thoroughly cleansed, and also to allow the orifice (a) to be placed (longitudinally) in any position relative to the pendant or bracket to which it may be attached, and forms the mingling reservoir.

I do not desire to claim broadly the self generating burner, as the principle of this has long been known. Neither do I wish to claim the conical pointed adjusting screw (h) which forms the regulatin valve for the flow of the vapor, and when c osed forces out all accumulation from the passage way (f), as this particular feature is seen in a self generating gas burner which is delineated and described as Mr. Hollidays invention,-in the Practical Mechanics J oamal, published at Glasgow, in the year 1848 and 1849, page 180, and is also seen in D. H. Carpenter (New York) patent, dated May 25th 1858.

I am aware that self generating fluid gas burners for fluid lamps have been made separate from the wick tubes, and combined therewith in a manner similar to the combination of my generator (d) with the wick tube (0) having no air and vapor mingling reservoir within which to cool and condense the resinous or other adhering substances likely to adhere to the interior surfaces of said mingling reservoir and burner. But I am not aware that adjustable cap burners have been combined with an air, and hydro carbon vapor, reservoir, for the purpose of access to the interior of said reservoir, and exit orifice for cleansing them-or for any other purpose. I do not therefore claim adjustable cap burners except when used in combination with air and vapor mingling reservoirs or chambers for the purpose of cleansing the interior of said reservoir and burning orifice of such adherin substances as are condensed by the coldair 1n the mingling chamber. Nor do I claim a damper as a device-or for regulating the quantity of air to be mixed with hydro carbon vapor, nor do I claim a conic frustum of inclined planes as a device.

What I do claim as my invention4 and desire to secure by Letters Patent is,

The combination in a vapor burner of a conic frustum i, and draft holes, 70, substantially as specified in combination with the orifice n,-and damper o-the whole being constructed and combined substantially as and for the purposes specified and shown.
